howdy all, hope your day is good...stupid little problem, recurring check engine light, usually after warm up, and sitting stuck in traffic, reader pulls codes PO 442 and PO455, which translate to leak(small and large) in evaporative control system..I imagine a loose/tired rubber line somewhere, can anybody point me in the right direction to begin checking? thankyou in advance

You might need a new gas cap. The seal dies after 10 years of use, petrolium jelly on the seal will help for a while.

Also check the vacuum lines going into the charcoal cannister. It is under the aircleaner/battery area. The elbows tend to crack with age.
